Cisco 2801 router not recognizing image on CompactFlash card

Sam Brynes · ‎11-18-2019

I copied the image c2801-entservicesk9-mz.151-4.M7.bin to the compact flash card using a computer, but the 2801 router doesn't recognize it for some reason. It's a 64 MB SimpleTech CF card.

When I took it over to a different router (a Cisco 1841), it had no problems reading the card.

To be sure, I formatted the card in the 1841, and then copied over the image via TFTP to the card again.

I tested the CompactFlash card in two different 2801 routers, and both are having the same issue.

That's the reason why it doesn't work. The CF card may not be supported on the hardware.

Try looking for a Verbatim 2Gb CF.

I thought all CF cards were supported on Cisco devices, provided that the capacity wasn't too big?

Martin L · ‎11-19-2019

have you tried format it on the router itself ?

Sam Brynes · ‎11-19-2019

I tried formatting it on the Cisco 1841. I couldn't find a way to format it in ROMMON mode on the Cisco 2801. I don't have a CF card that the 2801 recognizes, so I can't boot into the IOS on the 2801 to format it from there.

hola:

Apenas prendas el router Control + Brak:

en Modo:

rommon 1> confreg 0x2102

1.- cargar en tu PCs uns ervidro TFTP: yom uso el TFTPD64

lo cargas y anotas el IP: x.x.x.x que debe de ser de tu PCS donde estas tratando de recuperar el sistema del router

Las variables necesarias para usar tftpdnld son:

IP_ADDRESS: la dirección de IP de la interfaz LAN
IP_SUBNET_MASK: la máscara de subred de la interfaz LAN
DEFAULT_GATEWAY: el gateway por defecto de la interfaz LAN (Si se está conectados al router por consola, el gateway es la IP del ordenador)
TFTP_SERVER: la dirección de IP del servidor TFTP.
TFTP_FILE : el nombre de la imagen del IOS en el servidor

ojo mucho cuidado con esto falta este pequeño detalle cuando sale que no reconoce la memoria FLash: flash:(default) del router ojo agregar este paso del SET:

TFTP_DESTINATION: The flash destination device for the file
flash:(default), usbflash0:

agregar a los anteriores ese y quedaría así :

TFTP_DESTINATION: flash:
